Description

The Patriot Defense Upper/Lower receiver starts life as a solid block of aerospace grade 7075 T6 aluminum alloy. Precision machined on a 4 axis CNC machine, hand finished and then anodized with type III hard anodize per the military spec.

The heart of our Competition Ready Carbine platform utilizes a Lilja AR10740 416 stainless barrel with a 1-8 twist. The barrels are threaded for and furnished with a pinned barrel extension with proper headspace, gas port hole drilled and finished with a target crown at the muzzle. The muzzle end is also threaded 5/8″ x 24 TPI to accept standard 30 caliber suppressors or muzzle brake devices. Currently our competition ready carbine are offered in a 20″ and 24″ model on our AR10 platform system.

Our AR-10 Bolt and Carrier Systems are treated with nickel boron (NIB-X), a revolutionary surface technology that provides permanent dry lubricity. This radically improves the performance of your AR-10 and eliminates the need to apply oil or grease to treated parts as regularly for the life of the weapon. Treated parts include; Bolt, Semi-Auto Bolt Carrier, Semi-Auto Hammer, Extractor, Cam Pin, Carrier Key and Firing Pin.
